Removal of arsenic (V) from aqueous solution by using silylated MCM-41 / Nurul Asnyirah Roslan

In this study, MCM-41 was synthesized by using cetyltrimethylammonium bromide (CTAB) as structure directing surfactant, functionalized with trimethylchlorosilane and used as adsorbent for the toxic metal ions i.e. arsenic (V) in aqueous solution. The synthesized and functionalized MCM-41 was charact...
